Download or read book Introduction to Tropical Geometry written by Diane Maclagan and published by American Mathematical Society. This book was released on 2021-12-13 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical geometry is a combinatorial shadow of algebraic geometry, offering new polyhedral tools to compute invariants of algebraic varieties. It is based on tropical algebra, where the sum of two numbers is their minimum and the product is their sum. This turns polynomials into piecewise-linear functions, and their zero sets into polyhedral complexes. These tropical varieties retain a surprising amount of information about their classical counterparts. Tropical geometry is a young subject that has undergone a rapid development since the beginning of the 21st century. While establishing itself as an area in its own right, deep connections have been made to many branches of pure and applied mathematics. This book offers a self-contained introduction to tropical geometry, suitable as a course text for beginning graduate students. Proofs are provided for the main results, such as the Fundamental Theorem and the Structure Theorem. Numerous examples and explicit computations illustrate the main concepts. Each of the six chapters concludes with problems that will help the readers to practice their tropical skills, and to gain access to the research literature. This wonderful book will appeal to students and researchers of all stripes: it begins at an undergraduate level and ends with deep connections to toric varieties, compactifications, and degenerations. In between, the authors provide the first complete proofs in book form of many fundamental results in the subject. The pages are sprinkled with illuminating examples, applications, and exercises, and the writing is lucid and meticulous throughout. It is that rare kind of book which will be used equally as an introductory text by students and as a reference for experts. —Matt Baker, Georgia Institute of Technology Tropical geometry is an exciting new field, which requires tools from various parts of mathematics and has connections with many areas. A short definition is given by Maclagan and Sturmfels: “Tropical geometry is a marriage between algebraic and polyhedral geometry”. This wonderful book is a pleasant and rewarding journey through different landscapes, inviting the readers from a day at a beach to the hills of modern algebraic geometry. The authors present building blocks, examples and exercises as well as recent results in tropical geometry, with ingredients from algebra, combinatorics, symbolic computation, polyhedral geometry and algebraic geometry. The volume will appeal both to beginning graduate students willing to enter the field and to researchers, including experts. —Alicia Dickenstein, University of Buenos Aires, Argentina

Download or read book American Tropics written by Megan Raby and published by UNC Press Books. This book was released on 2017-10-03 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiversity has been a key concept in international conservation since the 1980s, yet historians have paid little attention to its origins. Uncovering its roots in tropical fieldwork and the southward expansion of U.S. empire at the turn of the twentieth century, Megan Raby details how ecologists took advantage of growing U.S. landholdings in the circum-Caribbean by establishing permanent field stations for long-term, basic tropical research. From these outposts of U.S. science, a growing community of American "tropical biologists" developed both the key scientific concepts and the values embedded in the modern discourse of biodiversity. Considering U.S. biological fieldwork from the era of the Spanish-American War through the anticolonial movements of the 1960s and 1970s, this study combines the history of science, environmental history, and the history of U.S.–Caribbean and Latin American relations. In doing so, Raby sheds new light on the origins of contemporary scientific and environmentalist thought and brings to the forefront a surprisingly neglected history of twentieth-century U.S. science and empire.

Download or read book Essentials of Tropical Combinatorics written by Michael Joswig and published by American Mathematical Society. This book was released on 2021-12-08 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this book is to explain, at the graduate student level, connections between tropical geometry and optimization. Building bridges between these two subject areas is fruitful in two ways. Through tropical geometry optimization algorithms become applicable to questions in algebraic geometry. Conversely, looking at topics in optimization through the tropical geometry lens adds an additional layer of structure. The author covers contemporary research topics that are relevant for applications such as phylogenetics, neural networks, combinatorial auctions, game theory, and computational complexity. This self-contained book grew out of several courses given at Technische Universität Berlin and elsewhere, and the main prerequisite for the reader is a basic knowledge in polytope theory. It contains a good number of exercises, many examples, beautiful figures, as well as explicit tools for computations using $texttt{polymake}$.

Book excerpt: Described as 'rich and satisfying' by The Times, Brixton Beach is the story of an artistic young girl forced to leave war-torn Sri Lanka, only to find that the shadow of violence has followed her to London. 'An ambitious, lyrical novel' TLS Opening dramatically with the horrors of the 2005 London bombings, this is the profoundly moving story of a country on the brink of civil war and a child's struggle to come to terms with loss. London. On a bright July morning a series of bombs bring the capital to a halt. Simon Swann, a medic from one of the large teaching hospitals, is searching frantically amongst the chaos and the rubble. All around police sirens and ambulances are screaming but Simon does not hear. He is out of breath because he has been running, and he is distraught. But who is he looking for? To find out we have first to go back thirty years to a small island in the Indian Ocean where a little girl named Alice Fonseka is learning to ride a bicycle on the beach. The island is Sri Lanka, with its community on the brink of civil war. Alice's life is about to change forever. Soon she will have to leave for England, abandoning her beloved grandfather, and accompanied by her mother Sita, a woman broken by a series of terrible events. In London, Alice grows into womanhood. Trapped in a loveless marriage, she has a son. Slowly she fulfils her grandfather's prophecy and becomes an artist. Eventually she finds true love. But London in the twenty first century is a mass of migration and suspicion. The war on terror has begun and everyone, even Simon Swann, middle class, rational, medic that he is, will be caught up in this war in the most unexpected and terrible way.

Download or read book Analysis of Climate Variability written by H. von Storch and published by Springer Science & Business Media. This book was released on 1999-10-20 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various problems in climate research, which require the use of advanced statistical techniques, are considered in this book. The examples emphasize the notion that the knowledge of statistical techniques alone is not sufficient. Good physical understanding of the specific problems in climate research is needed to guide the researcher in choosing the right approach to obtain meaningful answers. The second edition of this book, originally based on contributions given during a school sponsored by the European Union on the Italian island of Elba, continues to be based on these general principles. The general outline has been kept the same, covering aspects such as the examination of the observational record, stochastic climate models, analytical techniques, e.g. EOF, teleconnections and so on, but the chapters have been revised and updated, in some cases extensively, to cover the advances in the field in the years since the first edition.

Book excerpt: A NATIONAL JEWISH BOOK AWARD FINALIST A Recommended Book From: The New York Times * Good Morning America * Entertainment Weekly * Electric Literature * The New York Post * Alma * The Millions * Book Riot A commanding debut and a poignant coming-of-age story about a devout Jewish high school student whose plunge into the secularized world threatens everything he knows of himself Ari Eden’s life has always been governed by strict rules. In ultra-Orthodox Brooklyn, his days are dedicated to intense study and religious rituals, and adolescence feels profoundly lonely. So when his family announces that they are moving to a glitzy Miami suburb, Ari seizes his unexpected chance for reinvention. Enrolling in an opulent Jewish academy, Ari is stunned by his peers’ dizzying wealth, ambition, and shameless pursuit of life’s pleasures. When the academy’s golden boy, Noah, takes Ari under his wing, Ari finds himself entangled in the school’s most exclusive and wayward group. These friends are magnetic and defiant—especially Evan, the brooding genius of the bunch, still living in the shadow of his mother’s death. Influenced by their charismatic rabbi, the group begins testing their religion in unconventional ways. Soon Ari and his friends are pushing moral boundaries and careening toward a perilous future—one in which the traditions of their faith are repurposed to mysterious, tragic ends. Mesmerizing and playful, heartrending and darkly romantic, The Orchard probes the conflicting forces that determine who we become: the heady relationships of youth, the allure of greatness, the doctrines we inherit, and our concealed desires.

Download or read book Interacting Climates of Ocean Basins written by Carlos R. Mechoso and published by Cambridge University Press. This book was released on 2020-11-26 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate variability in different ocean basins can impact one another, for instance the El Niño/Southern Oscillation (ENSO) in the Pacific Ocean has remote effects on other tropical oceans around the world, which in turn modulate ENSO. With chapters by eminent researchers, this book provides a comprehensive review on how interactions among the climates in different ocean basins are key contributors to global climate variability. It discusses how interbasin interactions are mediated by oceanic and atmospheric bridges and explains exciting new possibilities for enhancing climate prediction globally. The first part of the book covers essential theory and introduces the basic mechanisms for remote connection and local amplification. The second presents outstanding examples. The latter part discusses applications to cases of societal interest such as impacts on monsoon systems and expectations after climate change. This comprehensive reference is a useful resource for graduate students and researchers in the atmospheric and ocean sciences.

Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive text is a major synthesis on ecological change in the Gulf of Alaska. It encompasses the structural and annual changes, forces of change, long-ecological changes in the atmosphere and ocean, plankton, fish, birds and mammals, and the effects of the 1989 Exxon Valdez Oil Spill. With 5 major sections, Long-term Ecological Change in the Northern Gulf of Alaska first describes the physical features, the atmosphere and physical oceanography, the annual production cycle, the forage base for higher animals and trophic transfer, and the adaptations for survival in this changing environment for 9 portal species. Then, the major forces of change are introduced: climate, geophysics, fisheries and harvesting, species interactions, disease and contaminants. Next, the long-term records of change in physical factors and biological populations are presented, as well as the potential reasons for the biological changes. Following is the history of the Exxon Valdez oil spill and its long-term effects. And, finally, the emergent properties of the ecosystem are discussed and an attempt is made to weigh the importance of the major forcing factors in terms of their temporal and spatial scales of influence. * Examines important data on long-term change in the ecosystem and the forcing factors that are responsible for it * Provides an account of the 1989 Exxon Valdez oil spill with emphasis on the long-term effects * Describes the effects of climate change, geophysical change, species interactions, harvesting, disease, the 1989 oil spill, and marine contaminants on key populations of marine organisms
